If you weren't on XBox, I'd say bring her over for a little party . They usually get the hint after a few tries.
Yes, there was an old bug of an NPC shadowing you persistently - but that was old (like, before 2.0), and I never heard about them interdicting/attacking. Most likely, you made someone angry.
thanks for all the reply's much appreciated. i did have an old mission i completed but didn't turn in cause i was stacking them for big payout to share. one of them was not mining and sure enough it said hostile ships would be sent after you. didn't think that they would still follow you even though i turned in the cargo but i still never fully completed the mission. will not make that mistake again. thanks again.
